plotRTeX

Converts ggplot2 graphics to PDF using LaTeX. Relies on tikzDevice to create a tikzpicture and then compiles a LaTeX standalone document using PDFLaTeX. Works on Mac OS, requires PDFLaTeX.

How to Install

devtools::install_github("3wen/plotRTex")

How to

First create a ggplot graphic, then use the ggplot2_to_pdf() function to export it as a tex file and a PDF file.

economics_long <- 
mutate(economics_long, variable_tex = factor(variable,
                        levels = c("pce", "pop", "psavert", "uempmed", "unemploy"),
                        labels = c("$PCE_t$", "$N_t$", "$r_t$", "$\\bar{s}_t$", "$s_t$")))
